Almost five billion years ago matter coalesced in a nebula containing gases like hydrogen and helium and also  heavier elements of the form of dust. It is of course a difficult task to recreate the course of events, not many traces are left. The original nebula may have had a size of about 50 light years and theory says that it fragmented into bits a few light years in size. The matter collapsed and became denser. About 2 % was heavier elements, these must have been created in earlier star generations and subsequently been ejected in order to later become constituents in our forming solar system. Modern research adds to our knowledge by detailed studies of other stellar systems in formation.
